How are group 1 elements different from the group 18 elements?

Updated: 8/11/2023

The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.

how is group 18 different from the other groups

∙ 12y ago

the difference is that they are different types of metals, and group one is highly reactive and generally soft. Group two however is less reactive and is also harder.

Group 1: metals, highly reactive, don't exist in nature by themselves.

Group 18: gases, non-reactive, exist in nature in small amounts.

What are the two names for group 18 elements?

Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases

What are elements main features?

The main group elements are groups 1, 2, and 13 - 18.

How does the numbers of electrons change across a period of elements?

The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).

Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?

group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.

How Are Groups On A Periodic Table Numbered?

Groups on the periodic table are numbered from 1 to 18, with the group number corresponding to the number of valence electrons in the elements of that group. Group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on. Groups 1, 2, and 13-18 are known as the main group elements.

Elements in groups 1 and 2 of the periodic table are known as the alkali metals and alkaline earth metals, respectively. Elements in groups 13-18 are known as the boron group, carbon group, nitrogen group, oxygen group, halogens, and noble gases.

Which of the elements are representative elements in the periodic table?

Representative elements are the elements in groups 1, 2, and 13-18 of the periodic table. These elements are also known as the main group elements and have characteristic properties that make them unique. They are located on the left and right sides of the periodic table.

Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?

group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
